sorry to post the problem again Kernel : 2.6.10 patch-o-matioc: patch-o-matic-20051025 or patch-o-matic-20051025 iptables:1.3.3 first I user the POM's ./runme command to patch the kernel, then make menuconfig in linux kernel dir, and select connlimit module. when I make the kernel, it found errors when comblie to ipt_connlimit module. The follow is the error message ----------------------------------------------------------------- CC net/ipv4/netfilter/ipt_connlimit.o net/ipv4/netfilter/ipt_connlimit.c: In function `count_them': net/ipv4/netfilter/ipt_connlimit.c:68: error: structure has no member named `proto' net/ipv4/netfilter/ipt_connlimit.c:94: error: structure has no member named `infos' net/ipv4/netfilter/ipt_connlimit.c:101: error: structure has no member named `infos' make[3]: *** [net/ipv4/netfilter/ipt_connlimit.o] Error 1 make[2]: *** [net/ipv4/netfilter] Error 2 make[1]: *** [net/ipv4] Error 2 make: *** [net] Error 2 ---------------------------------------------------------- I want to know where the problem is. and Is the iptables's version conflict with the Linux kernel version? anybody use connlimit module can tell me what your kernel version, iptables version and the patch-o-matic's version. Thanks anyway
